The rational part of a teen’s brain isn’t fully developed and won’t be until age 25 or so. In fact, recent research has found that adult and teen brains work differently. Adults think with the prefrontal cortex, the brain’s rational part.

That’s right, your brain processing power and memory peaks at the age of 18, according to new research published in Sage Journals. Determined to find out the peak age for different brain functions, the researchers quizzed thousands of people aged from 10 to 90.
mental age, intelligence test score, expressed as the chronological age for which a given level of performance is average or typical. An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ).
Doctors may be able to warn patients if they are at risk of early death by analysing their brains, British scientists have discovered. They could then advise patients to change their lifestyle or start a course of treatment. …
Age 50: Being the go-to for information
The Psychological Science study found that 50 was the peak age for understanding information. And those people weren’t just rattling off facts, either.
The average child’s IQ is not stable until around four years of age. It may be much later in children who were born early or who have significant health issues.
It is customary to say that the mental age of the average adult is about sixteen years.
Emotional Development
At the age of 15, teens start to think about what it would be like to live out on their own. While some teens may be imagining college, others may be thinking about getting their own apartment. Your 15-year-old may become stressed about grades, relationships, and other teenage issues.
The scientists found that, in general, diseased brains appear older than healthy ones, revealing a gap between their predicted and their chronological ages. … In people with a neurological disorder, the brain appeared older than their chronological age. Genetic variation might explain some of this age gap.
Your brain ages faster if you’re depressed
The same aging is also present in a depressed person’s brain. … In doing so it can speed up the brain’s aging process, making depressed people more susceptible to illnesses associated with old age.
Brain Age, also known as Dr Kawashima’s Brain Training, is a series of video games developed and published by Nintendo, based on the work of Ryuta Kawashima.
The Prefrontal Cortex Gets Lit
Though your fast cognitive reflexes may be slowly eroding, at 25, your risk management and long-term planning abilities finally kick into high gear.
It’s strongly believed that once we hit 25, the brain’s plasticity solidifies. This makes it harder to create neural pathways, which can mean it’s tougher to learn new skills. However, we believe it’s possible to break apart rigid neural patterns in the brain.
Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals. Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take place well into one’s 20s.
The frontal lobes, home to key components of the neural circuitry underlying “executive functions” such as planning, working memory, and impulse control, are among the last areas of the brain to mature; they may not be fully developed until halfway through the third decade of life [2].
The brain’s capacity for memory, reasoning and comprehension skills (cognitive function) can start to deteriorate from age 45, finds research published on bmj.com today.
We found that the 4- to 12-year-old age groups showed the strongest learning effect measured by the raw RT difference scores. Around the age of 12, we found a striking transition to less pronounced sequence-specific learning, as measured by smaller differences between the responses to high and low frequency triplets.
Aging may also bring positive cognitive changes. For example, many studies have shown that older adults have more extensive vocabularies and greater knowledge of the depth of meaning of words than younger adults. … Research shows that older adults can still: Learn new skills.
Yes, your IQ can change over time. But [IQ] tests give you the same answer to a very substantial extent, even over a period of year. The older you are, the more stable your test score will be. … So the average IQ of a 20-year-old in 1947 was lower than the average IQ of a 20-year-old in 2002.
Not generally. IQ tests are age adjusted, basically to take account of youth and inexperience (under 18) or age and diminishing speed.
Few studies have examined the stability of intelligence differences from childhood or youth to older age using the same test. … Their results suggest that around half of the individual differences in intelligence are stable across most of the human life course.
The number actually represents how your results compare to those of other people your age. A score of 116 or more is considered above average. A score of 130 or higher signals a high IQ. Membership in Mensa, the High IQ society, includes people who score in the top 2 percent, which is usually 132 or higher.
Price, a professor at the Wellcome Trust Centre for Neuroimaging at University College London, and colleagues, tested 33 “healthy and neurologically normal” adolescents aged 12 to 16. Their IQ scores ranged from 77 to 135, with an average score of 112.
So, an 8-year-old who passes the 10-year-old’s test would have an IQ of 10/8 x 100, or 125. It constituted a revolutionary approach to the assessment of individual mental ability. However, Binet himself cautioned against misuse of the scale or misunderstanding of its implications.
The average score on an IQ test is 100. Most people fall within the 85 to 114 range. Any score over 140 is considered a high IQ. A score over 160 is considered a genius IQ.
Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/10 × 100, or 120. If the 10-year-old had a mental age of 8, the child’s IQ would be 8/10 × 100, or 80.
85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted. 145 to 159: Highly gifted.
